Abstract
in English, Portuguese

Objective: To determine the prevalence of smoking experimentation among adolescents with asthma or allergic rhinitis.

Methods: This was a cross-sectional study involving adolescent students (13-14 years of age) in the city of Belo Horizonte, Brazil. The participants completed the Centers for Disease Control and Prevention and International Study of Asthma and Allergies in Childhood questionnaires, both of which have been validated for use in Brazil. We calculated the prevalence of smoking experimentation in the sample as a whole, among the students with asthma symptoms, and among the students with allergic rhinitis symptoms, as well as in subgroups according to gender and age at smoking experimentation.

Results: The sample comprised 3,325 adolescent students. No statistically significant differences were found regarding gender or age. In the sample as a whole, the prevalence of smoking experimentation was 9.6%. The mean age for smoking experimentation for the first time was 11.1 years of age (range, 5-14 years). Among the adolescents with asthma symptoms and among those with allergic rhinitis symptoms, the prevalence of self-reported smoking experimentation was 13.5% and 10.6%, respectively.

Conclusions: The proportion of adolescents with symptoms of asthma or allergic rhinitis who reported smoking experimentation is a cause for concern, because there is strong evidence that active smoking is a risk factor for the occurrence and increased severity of allergic diseases.

Objetivo:: Avaliar a prevalência da experimentação de cigarro em adolescentes com asma ou de rinite alérgica.

Métodos:: Estudo transversal envolvendo escolares com 13-14 anos de idade na cidade de Belo Horizonte (MG). Os escolares preencheram os questionários do Centers for Disease Control and Prevention e do International Study of Asthma and Allergies in Childhood, ambos validados para uso no Brasil. Foram calculadas as prevalências de experimentação de cigarro na população geral estudada, naqueles com sintomas de asma ou de rinite alérgica e nos subgrupos em relação ao gênero e à idade da experimentação.

Resultados:: A amostra foi constituída por 3.325 adolescentes. Não houve diferenças estatisticamente significativas em relação ao gênero e a idade dos participantes. Na amostra geral, a prevalência da experimentação de cigarro foi de 9,6%. A média de idade da experimentação de cigarro pela primeira vez foi de 11,1 anos (variação, 5-14 anos). Nos adolescentes com sintomas de asma e de rinite alérgica, a prevalência autorrelatada de experimentação de cigarro foi de 13,5% e 10,6%, respectivamente.

Conclusões:: A proporção de adolescentes com asma ou rinite alérgica que relataram ter experimentado cigarro é preocupante, visto que há fortes evidências de que o tabagismo ativo é um fator de risco para a ocorrência e maior gravidade de doenças alérgicas.
